Answer:
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents
It was discovered in 1898 by Italian physician Camillo Golgi during an investigation of the nervous system. After first observing it under his microscope, he termed the structure as apparato reticolare interno.
Take two healthy potted plants. Keep them in a dark room for 2-3 days. Now place each plant in a separate glass. Get a cup containing potassium hydroxide by the side of the plants (the potassium hydroxide is used to absorb carbon dioxide). COver both plants with separate jars. Seal the jars so that the set-up-is-air-tight. Keep the plants in sunlight for two hours. Gently pluck a leaf from each plant. remove the chlorophyll from the leaves by boiling them in alcohol. Wash the leaves with water and then pour iodine solution over them.
We can conclude that the photosynthesis cannot be carried out without carbon dioxide. the leaf from the plant (which was the jar containing potassium hydroxide, which absorbed the carbon dioxide) turns blue black on iodine solution showing that starch is presented in this lead.
so this shows that carbon dioxide is necessary for the processs of photosynthesis to take place
Answer:
Surface Irrigation involves distributing water over the surface of the soil
Sprinkler Irrigation involves use of pressurized nozzles to spray water in a shower
Variable flow irrigation involves use of advanced version of sprinkler irrigation
Trickle Irrigation involves use of emitters to control the flow of water
Sub-irrigation involves the use of perforated pipes
Explanation:
Surface Irrigation involves distributing water over the surface of the soil by allowing water to flow into the farm from irrigation channels.
Sprinkler Irrigation involves use of pressurized nozzles to spray water in a shower on the plants.
Variable flow irrigation involves use of advanced version of sprinkler irrigation. It has a variable-flow control knob on it to vary the output and flow of water. It also ensures uniform water distribution.
Trickle Irrigation involves dripping water onto the soil at very low rates through a system of tiny pipes fitted with outlets called emitters or drippers in order to control the flow of water.
Sub-irrigation involves the use of perforated pipes to apply water below the soil surface in order to raise the water-table near the plant root zone as well as to remove excess water.
